Answer:An object that absorbs ALL radiation falling on it, at all wavelengths, is called a blackbody. When a blackbody is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. ... As its temperature increases further it becomes yellow, white, and ultimately blue-white

Answer:
,
(before collision),
(after collision).
Explanation:
The total momentum is obtained using the Principle of Momentum Conservation:

It is trivial to find that final speed and total momentum of the system are zero:

The total kinetic energy of the system becomes zero due to the inellastic collision and the same masses and speeds. Total kinetic energies before and after collision are, respectively:
